High end box



United States Patent O 3,259,295 HIGH END BOX James N. Butz, Farmington, Mich., assignor to Carroll Container Corporation, Detroit, Mich., a corporation of Michigan Filed Mar. 12, 1965, Ser. No. 439,295 3 Claims. (Cl. 229-23) This invention relates to shipping cartons and particularly to a shipping carton made from corrugated paperboard, or the like, for the shipment of large irregular objects.

It is an object of the present invention to provide a shipping carton of the above character in which one end of the carton is of a height greater than the other end of the carton.

Among the other objects of the present invention are the provision of a shipping container of the above character which is readily fabricated on commercially available machines of the type used for the cutting, scoring, and printing of corrugated paperboard, which is of sturdy construction, which utilizes a minimum amount of material, which occupies a minimum amount of space, which is inexpensive, which is conveniently assembled and fastened, which completely encloses an article packaged therein, and which is easily handled and transported.

These and other objects of the present invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings, wherein:

FIGURE l is a perspective view of a carton embodying the present invention, the carton being fully assembled and fastened together;

FIG. 2 is a View of the structure illustrated in FIG. l with the various top flaps and walls of the carton being shown in an open, unfastened position; and

FIG. 3 is a plan view of the unfolded sheet material from which the carton of FIGS. 1 and 2 is made, showing the cutting and scoring thereof.

Referring now to the drawings, the carton is shown as being made from two sheets of corrugated paperboard 4 and 5 which are so cut, scored, folded, and fastened, as to form an enclosed carton or box configuration having a low end portion 6 and a high end portion 8. The shapes of the high and low end portions 6 and 8 are dened by a front wall 10 and an identical rear wall 12. The front and rear walls 10 and 12 `are connected together at opposite ends of the box by a pair of end Walls 14 and 16. The front wall 10 and end wall 16 form a part of the sheet 5 and extend for the entire length of said sheet. The rear wall 12 and the end wall 14 form a part of the sheet 4 and extend for the entire length of this sheet. While the carton is illustrated as being formed from two separate sheets, it could be made from one sheet Where the size of the carton and the size of the available cutting and scoring equipment permit. It will be noted, however, that the illustrated carton makes use of two sheets 4 and 5 of the same length, which simplifies inventory problems. `In the assembly of the two sheets 4 and 5 an edge 18 of the end wall 16 is joined to an edge 20 of the rear Wall 12 by means of a piece of tape (not shown). Similarly, an edge 22 of the front wall 10 is joined to an edge 24 of the end wall 14 by means of a piece of tape 26 (FIG. 1). As will be apparent to those familiar with carton manulfacture, stitching or other fastening means may be used instead of tape, if desired. In folding the assembled sheets into the carton of FIGS. 1 and 2, the end wall 14 is folded along a score line 2S which demarks it from the rear wall 12 and the end wall 16 is folded along ya score line 28 which demarks it from the front wall 10. It will be noted that all score lines are shown in broken lines in FIG. 3. Of course, the end 3,259,295 Patented July 5, 1966 ICC walls 14 and 16 are positioned perpendicular to the front wall 10 and rear wall 12.

As will be apparent from FIG. 3, a bottom. wall 30 is hinged to the rear wall 12 by virtue of the formation of a score line 32 therebetween. The end wall 14 has hinged thereto a flap 34 delineated from the end wall 14 by a score line 38. The ap 34 will be seen to be separated from the ybottom wall 30 by a cut 36. The solid lines of FIG. 3 indicating a cut which merges with a score line terminate in an arrow to reiiect where the cut ends and the score begins.

The front wall 10 has hinged thereto a bottom wall 40 which is delineate-d from the front wall 10 by a score line 42. A bottom liap 44 is hinged to the end wall 16 by a score line 48 and is separated from the bottom wall 40 by a out indicated at 46.

As is shown in FIG. 3, the end wall 16 is provided with a bottom flap 50 which is hinged to the end wall 16 at a score line 52, and which is separated from a high end top wall 54 by a cut indicated at 56. The high end top wall 54 is hinged to the h-igh end portion of the front wall 10` by `a score line 58. The end wall 14 of the sheet 4 is provided with a top ap 60 which is delineated from the end Wall 14 by a score line 62. The flap 60 is separated from a low end top wall 64 by a cut indicated at 66. The low end top wall 6-4 is hinged to the rear wall 12 by a score line 68. Another low end top wall 70 is hinged to the front wall 10 by a score line 72 and is provided with a flap 74 hinged thereto at a score line 76.

The rear Wall 12 has a high end top Wall 78 hinged to the high end portion of the rear wall 12 at a score line 80. In addition, the rear wall 12 has connected thereto a high end closure panel 82 delineated from the rear Wall l12 by a score line 84. The score line 84 may be said to extend vertically from one end of an upper edge of a low end portion of the rear wall 12 to an upper edge of a high end portion of the rear wall 12 defined by the score line 80. The upper edge of the lower end portion of the rear wall 12 is defined in part by the score line 68 and in part by a cut 8'5 at which the panel 82 is separated from the rear wall 12. It will be seen that the end enclosure panel 82 has a side closure flap 86 hinged thereto and delineated therefrom by a score line 88 and also a top flap 90 hinged thereto by a score line 92. The top flap 90 is separated from the top wall 78 by a cut as indicated at 94.

In order to form the sheets 4 and 5 into the carton illustrated in FIGS. 1 and 2, it is necessary to join the two sheets together as previously indicated. FIG. 3 illustrates the inside surfaces of the various wall members to be formed from the sheets 4 and 5. Accordingly, the sheet 5 is laid over the sheet 4 with the edges 18 and 20 adjacent one another and with the edges 22 and 24 adjacent one another. In this position the bottom Walls 30 and 40 face one another and the top walls 78 and 54 face one another. The adjacent edges mentioned above may then be joined with tape 26. The carton is then ready for shipment to a user in a flat condition.

In order to set up the carton from the joined sheets 4 and 5, the sheets are first bent along the score lines 25 and 28 to position the end walls 14 and 16 perpendicular to the front and rear Walls 10 and 12. Next, the flaps 34 and 44 are bent inwardly perpendicular to the end walls 14 and 16. Then the bottom Walls 30 and 40 are bent inwardly perpendicular to the front and rear walls 10 and 12 so that they overlap one another. The bottom Walls 30` and 40 are joined together as by stapling. The carton is then ready for insertion of the article to be pack aged therein. While the carton of the present invention is suitable for packaging a wide variety of irregularly shaped objects, an automobile rear quarter panel (not shown) comprises a representative example of such an article. The article may be supported within the carton by any suitable interior packaging (not shown).

In order to close the carton, the top flap 60 is bent inwardly so as to lie perpendicular to the end wall 14. The low end top wall 64 is then bent inwardly perpendicular to the rear wall 12, and the low end top wall 70 is overlapped on the low end top wall 64 and its flap 74 bent to lie flatly against the outer surface of the rear wall 12. The flap 74 is then stapled or otherwise secured to the rear wall 12. In this connection, it will be noted that the innermost low end top wall `64 is of a length less than the low end portion 6 by an amount equal to the width of the high end closure panel 82 and its iiap 86. Thus, the top wall 64 would be insuicient by itself to cover the top of the low end portion 6. However, the low end top wall 70 is of the required length and accomplishes this purpose. Furthermore, the provision of its flap 74 insures complete closure along the edge left by the cut 85. The high end portion 8 of the box is closed by bending the high end closure panel 82 inwardly so that it lies perpendicular to the front and rear walls 10 and 12, respectively, and so that its Hap 86 is disposed flatly against the inner face of the front wall 10 adjacent to an edge 98 thereof. The flap 86 is then secured to the front wall 10 by staples, as indicated at 100. Next, the bottom flap 50 is bent inwardly so as to lie perpendicular to the front and rear walls 10 and 12 in a horizontal position. Finally, the high 'end top wall 78 is bent inwardly perpendicular to the front Wall 10 and the high end portion top wall 54 is overlapped iiatly onto the top wall 78 and fastened thereto by staples, stitching, or other suitable fastening means. Staples 102 are illustrated for this purpose in FIG. 1.

In securing the closure panel flap 86 to the front wall 10, it will be appreciated the the flap 86 may be positioned on the outer surface of the front wall 10, and that a variety of fastening means may be utilized. It will also be seen that hand holes 104 are provided in the front wall 10 and the rear wall 12 to facilitate the handling of the carton. Further, it is immaterial which of the high end top walls 54 or 78 is overlapped on the other, or which of the bottom walls or 40 is overlapped on the other.

While it will be apparent that the preferred embodiment herein illustrated is well calculated to fulfill th'e objects above stated, it will be appreciated that the invention is susceptible to modiiication, variation and change without departing from the proper scope or fair meaning of the subjoinedclaims.
